Humidity ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Humidity Ratio = Water Vapour Mass/Gas Mass
H = M_wv/M_gas
This formula uses 3 Variables

Variables Used

Humidity Ratio - (Measured in Kg of water vapour per Kg of air) - Humidity Ratio represents the ratio of the mass of water vapor to the mass of dry air in a mixture, expressing the absolute amount of moisture present in the air.
Water Vapour Mass - (Measured in Kilogram) - Water Vapour Mass is the amount of water vapor present in the air, typically measured in mass units such as kilograms or grams per cubic meter of air.
Gas Mass - (Measured in Kilogram) - Gas Mass refers to the amount of water vapor present in a gas mixture, typically measured in units like grams of water vapor per kilogram of dry air.

STEP 1: Convert Input(s) to Base Unit

Water Vapour Mass: 4 Kilogram --> 4 Kilogram No Conversion Required
Gas Mass: 5.3 Kilogram --> 5.3 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H = M_wv/M_gas --> 4/5.3

Evaluating ... ...

H = 0.754716981132076

STEP 3: Convert Result to Output's Unit

0.754716981132076 Kg of water vapour per Kg of air --> No Conversion Required

FINAL ANSWER

0.754716981132076 ≈ 0.754717 Kg of water vapour per Kg of air <-- Humidity Ratio

Saturated Humidity

Go Saturated Humidity = Actual Humidity/Relative Humidity

Actual Humidity

Go Actual Humidity = Saturated Humidity*Relative Humidity

Mass of Dry Air or Gas in Mixture

Go Gas Mass = Water Vapour Mass/Humidity Ratio

Mass of Water Vapor in Mixture

Go Water Vapour Mass = Humidity Ratio*Gas Mass

Humidity ratio

Go Humidity Ratio = Water Vapour Mass/Gas Mass

Humidity ratio Formula

Humidity Ratio = Water Vapour Mass/Gas Mass
H = M_wv/M_gas

What is significance of humidity ratio?

The humidity ratio is an important parameter in various fields such as meteorology, HVAC (heating, ventilation, and air conditioning), and industrial processes because it provides a direct measure of the moisture content in the air, independent of temperature.

How to Calculate Humidity ratio?

Humidity ratio calculator uses Humidity Ratio = Water Vapour Mass/Gas Mass to calculate the Humidity Ratio, The Humidity ratio formula is defined as the specific humidity or humidity ratio of an air sample is the ratio of the weight of water vapor contained in the sample compared to the weight of the dry air in the same sample. Humidity Ratio is denoted by H symbol.

How to calculate Humidity ratio using this online calculator? To use this online calculator for Humidity ratio, enter Water Vapour Mass (M_wv) & Gas Mass (M_gas) and hit the calculate button. Here is how the Humidity ratio calculation can be explained with given input values -> 0.363636 = 4/5.3.

FAQ

What is Humidity ratio?

The Humidity ratio formula is defined as the specific humidity or humidity ratio of an air sample is the ratio of the weight of water vapor contained in the sample compared to the weight of the dry air in the same sample and is represented as H = M_wv/M_gas or Humidity Ratio = Water Vapour Mass/Gas Mass. Water Vapour Mass is the amount of water vapor present in the air, typically measured in mass units such as kilograms or grams per cubic meter of air & Gas Mass refers to the amount of water vapor present in a gas mixture, typically measured in units like grams of water vapor per kilogram of dry air.

How to calculate Humidity ratio?

The Humidity ratio formula is defined as the specific humidity or humidity ratio of an air sample is the ratio of the weight of water vapor contained in the sample compared to the weight of the dry air in the same sample is calculated using Humidity Ratio = Water Vapour Mass/Gas Mass. To calculate Humidity ratio, you need Water Vapour Mass (M_wv) & Gas Mass (M_gas). With our tool, you need to enter the respective value for Water Vapour Mass & Gas Mass and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
